Getting around Azeroth on a cool mount is half the fun in World of Warcraft, and the Stormcrow Thrayir, Eyes of the Siren, is one of the coolest. This isn't the first raven mount, but its Siren Isle origins make it special. This mount is tied to a stormy weather event on Siren Isle (part of the War Within expansion), occurring in multiple phases. You'll need to collect five Runekeys scattered across the island during these storms. Here's how to get this awesome flying mount:
How to Obtain Thrayir, Eyes of the Siren in World of Warcraft

The Whirling Runekey: This drops from the rare spawn Ksvir the Forgotten, found in the Forgotten Vault's southernmost room during a Storm.
The Torrential Runekey: Collect seven Torrential Fragments from any enemy on Siren Isle during a Storm phase.
The Thunderous Runekey: Gather five Thunderous Fragments from any chest on Siren Isle (Storm not required for chests).
The Cyclonic Runekey: Found while fishing on Siren Isle during a Storm, or as a possible drop from Zek’ul the Shipbreaker in the Deadfin Mire.
The Turbulent Runekey: Requires three Turbulent Fragments from specific locations near Kul Tiran ghosts:
- Behind the abandoned inn, dig in the garden.
- Inside a cave in the Rotting Hole (the ghost is cowering).
- Inside the Spirit-Scarred Cave (the ghost offers the fragment).

Once you've collected all five Runekeys, head to the Forgotten Vault on Siren Isle only during the Seafury Tempest phase. Entering during other phases won't trigger the ritual. In the eastern room, you'll find Thrayir on a platform with five runestones. Insert the corresponding Runekeys, and you'll receive the "Thrayir, Eyes of the Siren" quest. Complete the quest to claim your mount!
